This study aimed to look into the impact of continuous self-assessment on the self-efficacy beliefs of undergraduates studying English as a foreign language (EFL). To find out if there is a change in students’ beliefs about their language proficiency perception, the research was undertaken with 102 participants at the school of foreign languages of a private university. It was designed as quasi-experimental research utilizing qualitative and quantitative research methods to collect data through a self-efficacy scale, self-assessment questionnaire, and self-reflection checklists. The control and experimental groups were administered a self-efficacy scale at the beginning and the end of the term. Throughout the term, the participants in the experimental group assessed themselves weekly through self-reflection checklists and a self-assessment questionnaire. Based on the overall results, it was found that when the students had an opportunity to identify their strengths and weaknesses during a skill-based task through self-assessment questionnaires, they had a better sense of mastery related to that task. This inevitably led to an increase in their self-efficacy beliefs in terms of four skills, namely reading, writing, listening, and speaking as well as grammar.

The advent of the "positive psychology turn" in applied linguistics has brought increased attention to psychological constructs such as hope, which significantly impact students’ academic performance, including their effort. However, the intricate relationships among these factors remain underexplored. To address this gap, the present study employs a mixed-methods approach to investigate how specific dimensions of students' hope influence their efforts. A sample of 711 Chinese senior high school students studying English as a foreign language participated by completing questionnaires assessing their levels of hope and effort. Findings from structural equation modeling indicate that pathways, a dimension of hope, directly and positively affect students' efforts in learning a foreign language. This research provides valuable insights for educators, highlighting the importance of fostering hope in English learning to enhance students' strategic approaches to language acquisition and support their academic progress.
